AmSerialChart

---

AmSerialChart is the class you have to use for majority of chart types. 

The supported chart types are: line, area, column, bar, step line, smoothed line, candlestick and OHLC. 

The chart can be rotated by 90 degrees so the column chart becomes bar chart. 

The chart supports simple and logarithmic scales, it can have multiple value axes. 

The chart can place data points at equal intervals or can parse dates and place data points at irregular intervals.

addLegend 메소드 설명

Adds a legend to the chart. By default, you don't need to create div for your legend, however if you want it to be positioned in some different way, you can create div anywhere you want and pass id or reference to your div as a second parameter. (NOTE: This method will not work on StockPanel.)
